public class DeepEqual extends CollatingFunction implements Callable
| Modifier and Type | Field and Description |
|---|---|
static int |
COMPARE_ANNOTATIONS
Flag indicating that elements and attributes must have the same type annotation to be considered
deep-equal
|
static int |
COMPARE_ID_FLAGS
Flag indicating that the is-id and is-idref flags are to be compared
|
static int |
COMPARE_STRING_VALUES
Flag indicating that elements and attributes should always be compared according to their string
value, not their typed value
|
static int |
EXCLUDE_VARIETY
Flag indicating that the variety of the type of a node is to be ignored (for example, a mixed content
node can compare equal to an element-only content node
|
static int |
EXCLUDE_WHITESPACE_TEXT_NODES
Flag indicating that whitespace text nodes are ignored when comparing element nodes
|
static int |
INCLUDE_COMMENTS
Flag indicating that comment children are taken into account when comparing element or document nodes
|
static int |
INCLUDE_NAMESPACES
Flag indicating that two elements should only be considered equal if they have the same
in-scope namespaces
|
static int |
INCLUDE_PREFIXES
Flag indicating that two element or attribute nodes are considered equal only if their
names use the same namespace prefix
|
static int |
INCLUDE_PROCESSING_INSTRUCTIONS
Flag indicating that processing instruction nodes are taken into account when comparing element or document nodes
|
static int |
JOIN_ADJACENT_TEXT_NODES
Flag indicating that adjacent text nodes in the top-level sequence are to be merged
|
static int |
WARNING_IF_FALSE
Flag indicating that a warning message explaining the reason why the sequences were deemed non-equal
should be sent to the ErrorListener
